Title: Ink jet recorder
Inventor: SATO HIROAKI
IPC: B41J2/165
Filed: 1999-12-01
Abstract: PROBLEM TO BE SOLVED: To obtain an ink jet recording head in which clogging due to dry-up of ink can be prevented through a simple arrangement and sealing liquid can be removed and resupplied surely at a low cost. SOLUTION: A second edge 44 has a flat face at a part sliding on a nozzle face 28 and a blade 40 bends in accordance with the moving direction of a recording head 18 to abut against the nozzle face 28. The recording head 18 further slides on the second edge 44 to remove sealing liquid 34 applied onto the nozzle face 28 cleanly. Since the sealing liquid 34 can be removed positively from the nozzle face 28 even when high viscosity sealing liquid is applied thickly by attaching importance to the sealing performance of the nozzle face 28, ink 24 can be ejected smoothly. Since high viscosity sealing liquid can be used, the sealing liquid 34 is kept in nonvolatile state for a long term and sealing performance can be sustained while preventing clogging.

Title: Radar device
Inventor: YANASE SATORU
IPC: G01S7/34
Filed: 1993-12-15
Abstract: PURPOSE:To stably achieve target sensing and measurement of its position over a wide range of radar reflex section area by giving a plurality of targets respective appropriate STC characteristics. CONSTITUTION:Optimum STC level is decided when beam pursuit is to be started for the target captured, and the level information is stored/registered in a pursuit beam STC management circuit 3 in correspondence to the pursuit track No., and if track No. is fed thereafter at the time of beam pursuing, the pursuit beam STC information corresponding to the pursuit track is fed to an STC control information management circuit 4. Because this circuit is also fed with schedule information, an STC forming circuit is fed from the management circuit 4 with the optimum STC information due to the pursuit beam STC information corresponding to the track No. during each pursuit beam time in the schedule. Accordingly the optimum STC level set for each target is maintained while beam pursuit is continuing.

Title: Optical network
Inventor: SUNAGA YOSHINORI
IPC: H04B10/556
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To provide an optical network which executes transmission at high speed and also which is economically constituted. SOLUTION: Optical transmitters 32 and an optical receiver 13 are connected by an optical transmission path and optical signals are inputted from a plurality of optical transmitters 32 to one optical receiver 13 in the constitution of the optical network. In the optical network, the optical signals outputted form the optical transmitters 32 are pulse amplitude-modulated by respectively different frequencies, which are outputted from the respective optical transmitters 32 and the pulse cycles of the optical signals are permitted to be mutually different. The optical transmitters 32 are identified by the modulation frequencies. Even when a plurality of optical signals are inputted to the optical receiver 13 and beat noise is produced, the pulse cycles are different so that noise is reduced.

Title: Ink-jet head
Inventor: MAKITA HIDEYUKI
IPC: B41J2/055
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To process slits well without giving rise to a break to a piezoelectric element by setting the layer type piezoelectric element formed of lead titanate zirconate on a substrate formed of barium titanate ceramic. SOLUTION: A driving unit 1 has a plurality of layer type piezoelectric elements 12 arranged in two rows and united on a substrate 11 of barium titanate ceramic. A frame member 13 of resin, ceramic or the like surrounding the periphery of the piezoelectric elements 12 in two rows is bonded by an adhesive. The layer type piezoelectric elements 12 include 10 or more layers, with having lead titanate zirconate (PZT) 20 and internal electrodes 21 of silver palladium (AgPd) layered alternately. Since the same material as the piezoelectric elements 12, i.e., barium titanate ceramic is used for the ceramic substrate 11 to which the piezoelectric elements 12 are united, slits can be relatively easily processed with the use of lead titanate zirconate of a larger piezoelectric constant in the piezoelectric elements 12.

Title: Bouncing luminant
Inventor: NAKAMATSU YOSHIRO
IPC: A47K7/00
Filed: 1993-12-07
Abstract: PURPOSE:To obtain the small-sized and inexpensive luminant capable of sufficiently cleaning an ear due to its ability to take in light energy of the outside even during cleaning the ear and strongly emit light in application thereof to an earpick, etc., by connecting plural luminous parts with an optical path. CONSTITUTION:This bouncing luminant has plural luminous parts and an optical path connecting the parts. Specifically, in the case of, e.g. an earpick, the earpick body is formed of a transparent acrylic resin, etc., and earpick parts 2 and 3 at both ends thereof are formed of the acrylic resin, etc., containing a luminous unit 5 prepared by mixing 0.01-1% Mn, etc., as an activator in calcium sulfide, etc. Thereby, when the earpick parts 2 and 3 are preilluminated with light, the luminous unit 5 accumulates light energy to emit the phosphoresence itself. The light from the earpick parts 2 and 3 passes through the optical path composed of a transparent gripping part 4 to mutually bounce. As a result, light is strongly emitted.

Title: Bag-in-box internal container
Inventor: ICHIKAWA MAKOTO
IPC: B65D77/04
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To surely prevent degradation of a content caused by oxygen by providing an inner container of a multiple or multi-layered structure, and arranging a deoxidizing means between plastic films to form the inner container to effectively and easily remove the outside air and oxygen in a head space. SOLUTION: An inner container of double structure is stored inside an outer container 7, and a small bag packaging a deoxidizing agent 2 as a deoxidizing means is attached using an adhesive tape 3 between an outer-layer film 10 and an inner-layer film 11. The deoxidizing agent 2 can be attached not only by the adhesive tape, but also with an adhesive or by thermal fusion. The deoxidizing agent 2 is arranged on an upper surface of bag-in-box to efficiently remove oxygen in a head space not in contact with a content. In addition, invasion of oxygen from the outside, and degradation of the capacity of the deoxidizing agent 2 are prevented by setting the total oxygen permeability of the outer plastic film 10 outside the deoxidizing agent 2 to be smaller than the total oxygen permeability of the inner plastic film 11.

Title: Ink-jet pen and its operation method
Inventor: BURUUSU KAUGA
IPC: B41J2/045
Filed: 1989-12-28
Abstract: PURPOSE: To obtain an ink jet pen durable against repetitive temperature fluctuation without causing any ink leakage by providing an ink pickup tube extending from an ink reservoir to a catchbasin of the pen. CONSTITUTION: An ink pickup 42 is formed in a part 44 between an ink reservoir 12 and a catchbasin 22 while extending into the corner 46 thereof. When a pen is inclining, expanded air in the reservoir 12 pushes out ink through a bubble generator orifice to the catchbasin 22 where ink is caught and pushed out through the ink pickup 42 only when the end part thereof is wet. When the in the reservoir 12 is driven through the orifice 24 into the catchbasin 22, ink level in the catchbasin increases to wet the end of the ink pickup tube 42 thus feeding ink from the tube. When the volume of air in the reservoir 12 is contracted, ink is fed again to the reservoir 12 by the ink pickup 42 immersed into the ink.
